Table 1 Temporal evolution of hemodynamic characteristics obtained longitudinally in a rabbit model. Cardiac output (CO) from each experimental group was quantified by 2D PC-MRI in the ascending aorta. Measured mean blood pressure (MBP) and pulsatile pressure (PP) from the catheter at final week (TP-4) and estimated at younger ages based on obstruction level % (TP-1, 2, and 3). Additional details related to branch blood flow distributions and pressures are provided in the Supplemental Materials.
